We usually get a lot of questions on Oracle Exalogic Elastic Cloud Software (EECS) for Oracle SuperCluster – what is it, where can we use it, how do we install it, etc. Just recently someone asked me, “We have procured a new SuperCluster T5-8 rack. We also have EECS licenses. Now what do we do next? How do we get EECS up and running on this rack? “. In general, there seems to be some mystery surrounding EECS for SuperCluster. This post will help address questions like these.
Oracle Engineered Systems are designed and optimized to run specific workloads. Oracle SuperCluster is our SPARC-based Engineered System that combines the power of Oracle Exadata for running the database tier, and Oracle Exalogic for running the application tier in a single rack. SuperCluster integrates with optional EECS to run business applications and middleware components better and faster.
So what is EECS for SuperCluster? Simply put, EECS for SuperCluster has two distinct parts:
1. EECS Optimizations built in to Oracle Fusion Middleware products like WebLogic, Coherence and Tuxedo, designed to make your applications run a lot faster and better on SuperCluster
2. Oracle Traffic Director (OTD), a highly available software load-balancer over InfiniBand network fabric. OTD front-ends all requests coming in to the SuperCluster Rack and balances the load across multiple application instances running within the rack, keeping the traffic over high-speed InfiniBand fabric at all times
So where can I use Exalogic Software on SuperCluster? There are two primary use cases:
1. Improve performance and reliability of your business applications using EECS Optimizations. These optimizations, license-restricted to EECS only, are actually built in our upper stack Fusion Middleware products like WebLogic, Coherence, Tuxedo, etc. They are very easy to use. There is no EECS software to install. No code changes needed. All you need is the EECS license, and a few configuration changes, some of them as simple as turning on a switch from an admin console or inside a configuration file. And you will see up to 10 times better performance and reliability for Java and Fusion Middleware-based applications – Oracle apps, ISV Apps and custom Apps.
2. Load balancing over InfiniBand fabric using Oracle Traffic Director (OTD). OTD is our software load balancer and gives you the ability to load balance requests across multiple application instances running inside a SuperCluster rack. Your EECS license entitles you to download, install and use OTD software on SuperCluster. OTD is fully integrated with WebLogic. It is the best load balancer to front end multiple WebLogic managed servers. It can detect WebLogic server instances going down and can automatically route requests to remaining healthy servers. OTD can also be used as a reverse proxy.
To summarize, EECS on SuperCluster is
- Easy to use
o EECS Optimizations built in Fusion Middleware products, no EECS installation needed
o These are license-only entitlements. So all you need is the EECS license
o Can be used with simple configuration changes, as simple as turning on a switch
- Offers unmatched benefits
o Up to 10 times better application performance & reliability
o Oracle Traffic Director – Built-in high speed software load balancer on IB, at no extra cost
o Supports sub-capacity licensing
